Postpartum hypertension and preeclampsia

She was fine when you discharged her. Day 8, she is back in the emergency department with a headache she describes as "the worst of my life", a blood pressure of 172/114 mmHg and a baby feeding in the cubicle beside her. She had a mildly raised pressure in labour that settled by morning, so nobody put a plan in the notes. This topic is about the days after the placenta is out — the phase where the disease you thought you had finished quietly restarts.^[2][3]

Overview and definition

Two different clinical stories share one label, and the examiner wants you to separate them in your first sentence. ^[2][3]

• Persistent postpartum hypertension — she was hypertensive before or during birth and has not settled. The disease is old; the problem is control and duration.^[2]
• De novo postpartum hypertension — her pressures were normal throughout pregnancy and labour, and rise for the first time after birth. The disease is new, and the differential is wider.^[2][3]

Postpartum preeclampsia is new-onset hypertension after birth with any of the maternal end-organ features that define preeclampsia — so it is diagnosable without proteinuria, on renal, hepatic, haematological or neurological involvement alone. Keep the ISSHP framing in your head and simply move the clock past delivery.^[1]
